Why Is Welding Stainless Steel So Difficult

Welding Steel

Without a shadow of a doubt, many will tell you that stainless steel is definitely one of the best materials when it comes to strength and resilience. There are so many items you can develop by using it.

That’s precisely why, whenever you get the chance to utilize it, use it, because, with it, the possibilities are practically limitless. All you have to do is grab welder stainless steel and begin fusing the metal by employing a filler rod.

Even though it offers a plethora of benefits, unfortunately, those who have worked with it in the past will tell you that welding it can be extremely hard. But why is that? If you want to know the answer to this question, then just keep reading.

 

Various Challenges of Welding Stainless Steel

The Main Reasons Behind It

As it was previously mentioned welding stainless steel can be very demanding and hard, particularly in comparison to other metals. Of course, those who are experienced enough will tell you that you can weld stainless steel but prepare yourself for some hard work and obstacles. What’s so difficult about it?

There are many problems that may potentially arise during this process and below we will mention some of them:

  • One of the most common issues is when it twists while you’re heating it during the welding process. Additionally, it can warp afterward during the cooling process of welding. 
  • Besides that, you can potentially end up with pretty nasty welds, as well as weld marks on them. And that’s something that can make your entire build quite repulsive.
  • Furthermore, you could potentially have a problem with the high melting point of this steel. Namely, when you heat it, bear in mind, that you’ll be needing lots of heat to reach the melting point. And why is that a problem? Well, then you’ll be having problems with other metals you’re trying to add due to the fact that the heat can entirely melt them. Unfortunately, at times, it becomes literally impossible to weld stainless steel. 

 

Does It Have to Be That Challenging?

The answer to this question is sadly, yes and the reason behind it is very simple. Namely, it can become quite demanding due to the fact that stainless steel can withhold heat proficiently. And as we previously stated, this whole process is all about reaching high heat so you can add different types of metal. And it’s certainly very difficult to blend them.

Another reason why welding stainless steel is very hard is that you practically cannot make any mistake during the process. Fortunately, that’s not the case with other metals. With them, any error you make can relatively easily get hidden, however, you won’t be able to accomplish that with stainless steel. 

And that’s precisely one of the reasons why only the most seasoned welders can do it effortlessly. Those who have never done it before, or do not have enough experience should stay away from it, otherwise, they will easily mess something up.

 

Any Other Useful Information That Is Worth Mentioning?

Which Procedure Is the Most Convenient For Stainless Steel Welding?

Now, although everything we’ve written so far may seem a bit discouraging, don’t worry, there are still several ways you can successfully do this. But keep in mind that this highly depends on a couple of factors. 

First, ask yourself, what results do you want to accomplish? That’s crucial because different strategies bring different results and below, we’ll talk about the ones that are the most common: 

  • TIG Welding – If you opt for this one, then you will surely get the first-class weld. What’s great about it is the fact that it’s pretty versatile, plus the weld you receive are long-lasting. Additionally, this welding process involves low heat, which is an amazing option for thins sheets of stainless steel. Now, it’s worth mentioning that in order to do TIG welding, you need to be very experienced due to the fact that it’s a very complex process which is why no newbie will be capable of accomplishing it properly. Besides, this process is pretty slow, so you need to be very patient, plus it’s less cost-effective in comparison to other methods.
  • MIG Welding – This is another great option. With it, you’ll be able to quickly get amazing results, plus you do not have to be the biggest expert in the universe in order to do it. Unlike TIG Welding, this one is less expensive and the equipment you’ll be using is very practical and portable which means that you will get the job done without having any problems. But, let’s not forget to accentuate the downsides of it. The biggest one revolves around appearance. Bear in mind, that the final product is not going to be as appealing as it would be if you opted for TIG welding. Another major downside of it is the fact that the weld quality is not going to be as good as it would be with TIG welding.
  • Flux Core Welding – Generally speaking, this is a spectacular choice if you wish to avoid gas for the welding. The only thing you’ll be needing is the stainless flux core wire that is going to properly weld this steel, and of course, a great welder. One of the best things about it is the fact that it’s relatively easy to do, even if you’re a beginner. But there’s one thing that you should keep in mind, and that’s the fact you’re not going to be able to get very powerful and clean welds if you decide to employ this strategy. This one is mostly recommendable when you want to do some repair work. 
  • Stick Welding – If you’re just getting started when it comes to this, then try out this method first. It doesn’t require a lot of equipment, plus it’s pretty cheap and will allow you to get the job done. Just ensure to get the rod and welder for your purposes.

 

Even though all the facts that were mentioned here may sound a little bit scary, as you can see, although welding stainless still is very challenging, it is still doable, at the end of the day, so just arm yourself with patience and give it a try!
